Appearance settings dialog - Choose creation method by type
There are mainly 4 creation methods to choose from:
1. Use Preset Avatar
- Choose from pre-prepared human or animal avatars
- Suitable when you want to test quickly
2. Use 3D Model
- You can use
GLB / VRM / Splatas appearance - Choose from Media Library or specify URL directly
For 3D models, specify GLB / VRM / Splat from library or URL
3. Use Image
- You can use a still image as the AI Avatar's appearance
- Set by library selection or image URL specification
- You can also add image assets to switch during conversation as needed
In image mode, you can set assets to use during conversation in addition to idle image
4. Use Video
- You can use a video as the AI Avatar's appearance
- Set by library selection or video URL specification
- Like images, you can add assets to display during conversation and adjust appearance
In video mode, you can set the idle video
- If you want to test operation first:
Preset - If you want to use your own 3D avatar:
GLB / VRM / Splat - If you want to show character portraits:

Step 4: Configure Conversation Content
Once you've decided on the appearance, configure what and how the AI will speak.
📝 AI Text Chat Settings
Reply Language
- Set the language the AI Avatar will reply in (added in v1.15.0)
- Default is "Match user's language" — automatically replies in the language the user spoke
- If you want to fix to a specific language, such as Japanese-only spaces, select the language from the dropdown
Reply language dropdown in "AI Text Chat Settings"
System Prompt
- Enter a prompt that defines the AI's behavior and personality
- Writing role, speaking style, response scope, and prohibited items makes it more stable
- Example: "You are an information desk staff member. Respond in polite and plain language, and only answer within the scope you can guide without guessing."
- From the "History" button at the top right of the input field, you can recall previously entered prompts (added in v1.17.11. The same History button also appears on the "Supplementary Instructions for RAG" field)
- Write the role first
- Next write the tone
- Finally write "what to guide" and "what not to answer"
First Message (Added in v1.18.3)
- Set a fixed message to display first when a conversation with the AI starts
- If left blank, the AI will auto-generate it (consumes credits)
- Example: "Hello! How can I help you today?"
The "History" button on the system prompt and the "First Message" field
Step 5: Choose Voice Mode
🎙️ AI Voice Conversation Settings
Voice Mode
You can choose from the following 3 modes:
Voice mode selection - Choose type of voice synthesis
- No Voice Synthesis: Text chat only
- Standard Voice (TTS): Text-to-speech voice
- Real-time Voice: Real-time AI voice conversation (separate charge)
- For text-only interaction: "No Voice Synthesis"
- If voice reading is needed: "Standard Voice (TTS)"
- If natural voice conversation is needed: select "Real-time Voice"
Speech Recognition Language
When using voice mode, you can set the language to recognize user speech (added in v1.15.0).
- Default is "Default (follow browser language settings)" — automatically determined according to user's browser settings
- If voice misrecognition occurs or if the language used is determined, you can specify a fixed language code
Speech recognition language dropdown in "Speech Recognition Settings"
Examples of Fixed Specification
| Language | Language Code |
|---|---|
| Japanese | ja-JP |
| English (US) | en-US |
| Chinese | zh-CN |
- When English gets mixed in Japanese-only spaces
- When you want to narrow down to a specific language in multilingual spaces
- When you want to explicitly specify the language when voice misrecognition occurs frequently
Step 6: Configure Knowledge Base (Optional)
If you want to reference document files as AI knowledge, link the Knowledge Base in the "RAG / Knowledge Base Settings" section (added in v1.15.0).
"RAG / Knowledge Base Settings" section in AI Avatar edit screen
- Select the group to use from the "Knowledge Base to use" dropdown
- Enter additional instructions in "Supplementary instructions when using RAG" (optional)
Example supplementary instructions: "Decline if not in provided materials, add source file name at the end"
Knowledge Base group creation and document upload are performed on the "Knowledge Base" page.
Error Message Settings (Added in v1.18.3)
Opening "⚙️Error Message Settings" at the bottom of the edit dialog lets you change the message shown to users when an error occurs, per AI Avatar. If left blank, the default message is displayed.
You can individually set "Message when out of credits" and "Message for other errors"
| Item | Default Message |
|---|---|
| Message when out of credits | 💰You don't have enough conversation credits. Please contact the space administrator. |
